Volkswagen has acknowledged that it needs to make changes to its testing practices following the massive diesel scandal.

After announcing that the CO2 issue with its TDI models is much smaller than expected, the German automaker has outlined some changes it plans to make in hopes of avoiding another controversy. For starters, Volkswagen has admitted that “in the past, deficiencies in the processes have favored misconduct on the part of individuals,” adding that its test and certification processes have affected the company’s engine control devices.

As a result, Volkswagen is concentrating on structuring those processes more transparently and systematically. For example, future software for engine control devices will be developed strictly in accordance with the “4-eyes principle.” Those responsible for releasing the software will also be reorganized with more sharply defined and binding powers as well as responsibilities.

Looking back, Volkswagen admits that responsibilities were not sufficiently clear and there were deficiencies found in reporting and monitoring systems as part of its internal investigation. The company also plans on introducing new IT systems that allow individual processes to be monitored with greater efficiency and transparency. The new IT systems will also reduce Volkswagen’s dependence on individuals when problematic processes have to be identified.

Although the company’s analysis of its internal processes will be concluded shortly, more time is necessary for the external investigation to be completed. The automaker will provide a status update on the external investigation at its Annual General Meeting on April 21, 2016.

The recalls for the diesel scandal in Europe will begin in January 2016 starting with the highest-volume variant, the 2.0-liter TDI engine. The 1.2-liter TDI recall is currently scheduled to begin in the second quarter. As for the U.S., Volkswagen is still working with the EPA and CARB on a solution.
